Currently, the per-site profiles feature automatically tags pages with _current and _former based on whether a specific user is still a member of the site. These tags can be changed to whatever you want (e.g. _member and _non-member) in the site manager.

I wish that my wiki could automatically tag pages based on member type as well. For example:

Moderators: _moderator

Administrators: _admin

These should also be customisable via the site manager (for example, to "_manager" and "_owner").
